How much does the 2020 GMC Acadia cost?

Prices have softened 9.25% compared to this time last year, making it a favorable time to shop this model year.

There are 2,620 listings available, which suggests solid inventory for comparison shopping.

If you find a listing below $20,740.11, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2020 GMC Acadia a good car?

Yes — the 2020 GMC Acadia earns a 4.94/5 user rating and a 7/10 expert rating. The model scores 8/10 across Look and feel, Form and function, and Technology.

Drivers consistently praise the smooth and quiet ride, spacious interior, and comfortable family-trip demeanor. The upscale Denali trim also stands out in owner feedback, and the easy-to-use tech gets repeated approval.

The trade-offs are the price, the cargo-space complaints, and the sense that the value proposition is not especially strong. The overview also points to a model that aims to balance comfort, style, and available performance rather than maximize utility.

With 33.3% of listings marked as good or great deals, you have some room to shop selectively if you want the right combination of trim and price.

Is the 2020 GMC Acadia reliable?

Owners rate it 4.94/5, a strong signal of long-term satisfaction.

Owner feedback points to a dependable, trouble-free ownership experience centered on comfort, smooth operation, and a vehicle that many drivers feel good about keeping long term. The expert evaluation also emphasizes a refined, smooth powertrain and a well-tuned ride, which supports the sense that the Acadia is built to be easy to live with.

GMC also includes the first scheduled maintenance visit at no charge, which helps early ownership costs a bit.

For used buyers, the main long-term risk is less about outright durability and more about whether the vehicle’s condition and maintenance history justify the asking price.

What should I look for when buying a used 2020 GMC Acadia?

At 68.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle-history report and then prioritize a pre-purchase inspection, especially if you’re considering a higher-priced trim or a vehicle with a lot of equipment. Focus on condition, repair quality, and whether the features you want are actually present on the specific listing.

Key things to evaluate:

• Trim level: The base SL gives you the essentials, but it misses some of the more desirable driver-assistance features. The Denali adds a more upscale cabin treatment, while the AT4 brings a more rugged look and capability.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder, the SLT gets a turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, and AT4 and Denali models use a 310-hp 3.6-liter V6. The V6 is the smoothest and most refined choice, and it can tow up to 4,000 pounds.
• Safety package: Blind-spot warning and rear cross-traffic warning are standard, but forward collision warning and low-speed automatic emergency braking require an upgrade to SLT or AT4. The Driver Alert Package adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display.
• Infotainment: Every model gets Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot. Versions with an 8-inch touchscreen add a higher-resolution display, a simplified interface, and improved voice recognition.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the expert observed 20.1 mpg in mostly FWD use.

Which 2020 GMC Acadia trim should I buy?

The 2020 GMC Acadia is offered in 5 trim levels: SL, SLE, SLT, AT4, and Denali.

Here's the short version:

• Base trim: The SL is the entry point, but it lacks forward collision warning and low-speed automatic emergency braking. You still get blind-spot warning and rear cross-traffic warning, along with the core infotainment setup.
• Sweet-spot trim: The SLT is the best value if you want the turbocharged 2.0-liter engine and access to more advanced safety equipment. It adds meaningful capability without jumping all the way to the luxury end.
• Premium/top trim: The Denali is the most upscale choice, with the V6, available all-wheel drive, open-pore wood trim, and the most premium cabin presentation.
• Off-road trim: The AT4 is the one to choose if you want the rugged styling and dual-clutch AWD setup, but it’s less compelling if your driving is mostly everyday commuting.

The safety-package gap is important: forward collision warning and low-speed automatic emergency braking are not standard on the base trim.

Is now a good time to buy a used 2020 GMC Acadia?

This is a moderate, selective-buyer market, so you can shop carefully and still find opportunities.

• Deal availability: 33.3% of listings are priced as good or great deals.
• Inventory: There are 2,620 listings available.
• Price trend: Prices have softened 9.25% compared with last year.
• Clean inventory: 68.9% of listings are accident-free.

If you find a listing below $20,740.11, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 GMC Acadia's resale value?

The current average of $20,733 sits slightly below last year's $22,846.

That price movement suggests the Acadia has already absorbed some depreciation, which can help future sellers if they buy at the right number. If you pay close to the current average, your resale upside is more limited, but a well-bought example can still hold appeal because shoppers continue to value the Acadia’s comfort and family-friendly layout.

Vehicles with strong owner satisfaction ratings, like this model year's 4.94/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 GMC Acadia safe?

It earns five-star ratings in most NHTSA assessments, plus a four-star rollover resistance rating. The IIHS gives the Acadia high marks in the tests it has completed.

It earns a 6/10 safety score from our experts.

The standard safety setup includes rear-seat reminder, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning. If you want forward collision warning and low-speed automatic emergency braking, you need to move up to SLT or AT4, and the enhanced automatic emergency braking system is reserved for Denali.

The main caveat is that advanced driver-assistance coverage is thin for the base trim, so you should not assume every Acadia has the same safety equipment.

Should I buy a 2020 GMC Acadia or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 33.3% of listings are priced as good or great deals.
• At 68.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.25% compared with last year.
• Owners rate it 4.94/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, a new turbocharged engine, and updated technology.

Consider the 2019 if:

• At $17,551, the 2019 costs less than the current year's $20,733 average.
• It offers a more upscale interior and solid driving dynamics.

The bottom line: If you want the refreshed styling, updated tech, and broader trim mix, the 2020 is the better target. If your priority is spending less up front, the 2019 is the more budget-friendly path and still delivers the Acadia’s core family-friendly strengths.
